SkipperCollector has a post about 12" Lone Ranger and Tonto dolls. The horse-riding duo come from Disney, but you should view her post and read her description before going to the Disney site. I had a laugh-out loud reaction to her description of their undergarments ;-)
As you may have guessed, Hot Toys, has also got a Tonto for sale. You can see gorgeous photos of him at OneSixthScale Pictures and at Monkey Depot. Sideshow Collectibles is another dealer selling this figure. Price? The Hot Toys version costs $204.99 which does not include the $10.00 shipping fee. Gulp indeed.
